` j Y 2,451,811 CORNER FASTENER FOR PLASTER LATHS John L. Daily, Johnstown, Pa.

Application October 7, 1946, Serial No. 701,816

3 Claims.

The presen-t invention relates to wall constructions utilizing a plaster receiving base, such as plaster boards, plaster laths or the like yand more particularly to a corner fastener by means of which the plaster lath at the corners of a wall and lceiling are firmly held to ,prevent cracking or breaking of plaster when applied over the plaster lath.

An important object of the present invention is to provide a corner fastener of this character which eliminates the use of nails or other fastening devices which are difficult to apply in the corners of a wall construction.

A further object of .the invention is to provide a device of this character of simple and practical construction, which is efficient and reliable in use, relatively inexpensive to 'manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects :and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference be ing had to the accompanying drawings forming .part hereof, wherein like numerals refer to like parts throughout, and in which:

Figur-e l is a perspective View of a Wall conf struction sho-wing the fasteners in position at the corners thereof;

Figure 2 is a plan View of one of the fasteners;

Figure 3 is a perspective view thereof, and

Figure 4 is a fragmentary sectional View of the corner of the wall showing the fasteners in position as applied thereto.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a,- preferred embodiment of .the invention, the numeral 5 designates the corner fas-tener generally and which is formed of a single sheet of bendable metal and comprises arms 6 and 'I in longitudinal alignment and arms 8 and 9 likewise in longitudinal alignment, all of the arms lying in the same plane and forming an integral structure and each of the arms being disposed at right an gle-s t-o lan adjacent arm.

The arms 6 and 9 and arms 'I and 8 are bent along Ia diagonal fold line I0 .at the junction of the arm-s to provide a pair of V-Shaped fastening members I I and I2 with their narrow ends joined and with the said V-shaped fastening members positioned at right angles to each other as shown in Figure 4.

One longitudinal edge of each arm, adjacent its outer end, is formed with an inwardly struck prong I3.

The invention is designed primarily for use in ysecuring' the edges of the plaster boards or the like I4 at the corners of a room as well as at the corners of a ceiling, the plaster board being usuallir secured to its studding I5 in horizontal rows and one of th-e arms of Ithe fastener engages .one of the plast-er boards at the corner of four of the plaster boards as shown to advantage in Figure 1 of the drawings and with the -prongs I3 pressed into the plaster boards by the fingers of the builder whereby to firmly anchor the corner of the plaster boa-rds to each -oth-er in the manner as illustrated in Figure 4 of the drawings without requiring the use of nails or other fastening devices.

The corner fastener is secured to four different pieces of rock lath at the corner or ceiling of a room without the use of nails or other fastening devi-ces at the wall or ceiling angles an-d holds the rock lath together on both side walls where they meet in the angle and does not permit the plaster to crack when wood in the corners expands and contracts.

The fasteners may also be used to secure .the edges of the .plaster boards at the ceiling I6 to j the plaster boards at the side walls of the room.

From the foregoing it will be apparent that the fasteners may be easily and quickly placed in a desired position for securing .the edges of the plaster boards at the corners and ceiling of a room, after which `the plaster finishing I1 may be applied thereto to thus conceal the fasteners and to aid in securing the fasteners again-st the removal.

In View of the foregoing description .taken in f conjunction with .the accompanying drawings it is believed that a clear understan-ding of the device will be quit-e apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of .the invention as herein described and the scope of the appended claims.

What I claim as my invention is:

l. A wall fastener of .the class described comprising pairs of longitudinally aligned -arms formed from a single sheet of bendable metal, said arms being disposed at right angles with respect to each other and said arms being bent along a line connecting the vertex of one angle with that -of another yto provide a lpair of V-shaped fasteners in planes at righ-t `angles to each other for tting in the corner of a room, and prongs projectprising a plurality of integrally connected arms disposed at right angles .with respect -tlo each other and bent along la line connecting the vertex of one .angle with that of another to provide a pair of V-shaped fasteners in planes at right angles to each other for positioning in the corner of a room, and prongs struck from each of the arms alt :the `outer longitudinal edge thereof for embedding in -a Wall.
